T0 a/ZZ whom, it may concern.-

Be it known that I, JAMES HENRY SIM- MONS, a citizen of the United States, vand a resident of Talmo, in the county of Jackson and State of Georgia7 have invented a new and Improved Door-Lock, of which the following is a full, clear, and exact description.

This invention relates to improvements in door-locks, the objects being to provide a lock of simple construction that may be adjusted for either the right or left hand side of a door, that may be used as an automatic latch which may be opened by either knob, and that may be used as a lock operated from the inside knob and locked from the outside of the door without a key, but which cannot be unlocked from the outer side excepting with a suitable key.

Other objects of the invention will appear in the general description.

I will describe a door-lock embodying my invention and then point out the novel fea- Reference is to be had to the accompanying drawings, forming a part of this speciiication, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is an inner faceview of the working parts of a lock embodying my invention. Fig. 2 is a similar view, but showing the parts in different position. Fig. 3 is a central longitudinal section. Fig. 4 is an end view of one of the knob-sleeves employed. Fig. 5 shows one ofthe tumblers employed. Fig. 6 is a section on the line :r of Fig. 3. Fig. 7 is a section on the line y y of Fig. 3, and Fig. 8 shows another tumbler employed.

Referring to the drawings, 1 designates the casing of the lock, and 2 the bolt, mounted to slide therein, the said bolt having inward opposite extensions 3, which at their inner ends have inwardly-projected lugs 4, the purpose of which will be hereinafter described. At the outer side of the extensions 3, between their ends, are lugs or projections 5, designed to be engaged by a locking device, as will hereinafter appear. The bolt is moved outward by means of springs 6, which at one end engage with blocks 7 and at the other end with the head of the bolt. The locking member for the bolt consists of a yoke 8, having forward projections 9 for engaging with said lugs 5. At the opposite sides the yoke S has trunnions 10, which are mounted in bearing-blocks 11, secured in the locking-casing.

At the inner side the one end of a spring 12, the other end of said spring being attached to the lock-casing, and at its inner side the yoke has a projection 13, designed to engage against Veither side of a spring-clip 14, attached to an end wall of the lock-casing. This spring-clip 14 is of slightly greater strength than the spring 12, and therefore the spring 12 cannot overcome the resistance of the spring 14 and swing the yoke, but this spring 12, however, will add to the easy movements of the yoke. A square or angular spindle 15 extends through the lock-casing, and mounted on the inner end thereof but having sliding movement with relation thereto is a knob 16, while a knob 17 on the outer side of the door also has sliding connection with the spindle. The knob 16 is rigidly connected to a sleeve 18, the interior of which conforms to the angular spindle, but is slightly larger than the same, as clearly indicated in Fig. 3, so that there can be a slight rotary movement of the knob and sleeve relatively to the spindle.

Arranged on the inner end of the sleeve and of course within the lock-casing is a tumbler 19, having wings 20, which are spaced apart, and either one is designed to engage with an inward extension-block 21 in the yoke 8. It will be noted that the wings 20 are slightly beveled at one side, as indicated at 21H in Fig. 8, which is an inside view of the tumbler, so that said inclines will form cam-surfaces to pass freely over the projection A21 in theyoke, this projection being also slightly rounded on its side, designed to be engaged by said. wings to depress the yoke.

Opposite the space between the wings 20 the tumbler has a finger 22, designed to engage a lug 23, extended inward from the yoke 8 opposite the extension 21. The opening 24 in the tumbler through which the spindle 15 passes is somewhat larger in its general outline than the spindle, but at the corners of the openings are inward projections 25, with which the edges of the spindle are designed to engage after having a slight lost rotary movement in the opening 24.

The outer knob 17 iscOnnected to a sleeve 26, which passes through `an opening in the lock-casing, and connected to the end of this sleeve is a bolt-actuating tumbler 27, said tumbler having a central opening 28, through yoke is engaged by which the spindle passes, and on the side of the tumbler toward the outlet end of the lock-casing are wings or lugs 29, one of which is designed to engage with the lug 4 on one of the bolt extensions and the other end being designed to engage with the lug 4 on the opposite member, depending upon which direction the knob and spindle are rotated. Opposite the space between the wings 29 the tumbler 27 is provided with a iinger 30, the object of which is to move, as will be hereinafter described, the looking member for the boltinto locking position. The two tumblers are held yieldingly apart by means of a spring 31, which is coiled around the spindle and connects with the inner or adjacent surfaces of the tumblers.

In the operation of the lock as so far described the parts as shown in Figs. 1 and 3 are in position to lock the bolt 2 in its keeper, and at this time the locking member cannot be shifted from its locking position by any manipulation of the outer knob. It may, however, be released by the inner knob as follows: On the inner end of the sleeve 18 is a disk 32, having lugs 33 designed to engage between lugs 34 on the adjacent surfaces of the tumbler 19, the lugs on one part being of slightly less width than the space between the lugs on the other part, so as to permit for a slight lost motion of thesleeve 18-that is, thev motion between the disk 32 and the tumbler 19 must necessarily be slightly less than between the knob 16 and spindle 15, so as to allow the yoke 8 to be disengaged before the tumbler 27 is operated. Now by rotating the knob 1.6 one of the wings 20, depending upon the direction of'rotation, will engage with the inner extension 21 on the yoke 8, forcing the said. yoke to swing downward to bring the projection 13 underneath the clip 14, as indicated in Fig. 2. At this time the arms 9 on the yoke will be out of engagement with the lugs 5, and upon a further rotary movement of the inner knob 16, it being understood that at this time the wings 2O are free to move over the extension 21, thespindle 15will be rotated, causing one of the wings 29 on the tumbler 27 t-o engage with an inner projection or lug 4 on a bolt member, so that by further rotary movement both the inner and outer knobs will be turned and the bolt drawn out of its keeper. At this time it is obvious that the bolt may be manipulated from either the inner or outer side of. the door. When it is desired to relock the bolt from the inner side, the inner knob is to be forced inward, so that the linger 22 will engage with the lug or projection 23 in the forward portion of the lug 8. By a continued inward movement the arms 9 will be moved downward into engagement with the lugs 5 and the projection 13 will move to the opposite side of the latch 14, as indicated in Figs. 1 and 3, and thus the locking device will be held in engagement with said lugs or projections 5.

As before stated, the bolt-locking device cannot be released from the bolt by any manipulation of the outer knob. It may be moved to locking position, however, as follows: By pressing the outer knob inward the tumbler 27 will also be moved inward, so that the hnger 30 on the tumbler will engage with the projection 21 .of the yoke 8, andby a continued inward movement of the tumbler against the resistance of the spring 31 the locking member will be rocked to locking position. The said member may, however,'be moved out of its bolt-locking position by means of a suitable key passed through a keyhole 35 and engaged witha block 36, pivoted within the casing and having a cam-surface 37 for engaging with the yoke 8 at its front side. This cam-block is held yieldingly outward by means of a spring 38.

The device above described serves as both a latch and lock; but in some instances it may be desirable to employ it as a latch alone, so that when a door is swung closed it will automatically latch into the keeper. To change it from a lock to a latch, the inner knob is manipulated as first described-that is, to move the locking member out of engagement with the bolt so that the parts stand in position as indicated by dotted lines 39 in Fig. 3 and by full lines in Fig. 2. At this time the latch may be moved readily out of its keeper byturning the spindle by means of either one of the knobs, and as an inner sliding movement of the sleeves is not at this time desirable, as the same might accidentally release the locking member to engage it with the bolt, I pro'- vide means to prevent such contingency. As this means is'of similar construction for the two knobs and sleeves as shown in Fig. 3, a description of one will answer for both.

Secured on the casing is a disk 40, that is chambered on the inner side and has an opening through which the sleeve 18 passes. Movable in the chambered disk is a latch-arm 41, which at the inner portion is curvedto extend around the sleeve, and at the inner end of this latch is a lug 42, designed to engage the inner end of a sleeve 46, rigidly secured to IOO IIO

the knob, as shown in Fig. 3, and it is held in j such engagement by means of a spring 44. The free end of the latch device 41 extends outward from the disk and has a finger-piece 45 projected outward through a slot in the rim of the chambered disk, this slot being of suihcient depth to permit the latch device to be moved sufliciently inward to disengage its lug 42 from the sleeve 46, as indicated by dotted lines in Fig. 3. Bypushing the lug 42 outward from the sleeve the knob may be moved inward, as the lug will beheld out of its latchingengagement by bearing on the outer side of the sleeve.
